<p>All facilities that return errors from remote methods (such as
<a class="link" href="GDBusConnection.html#g-dbus-connection-call-sync" title="g_dbus_connection_call_sync ()"><code class="function">g_dbus_connection_call_sync()</code></a>) use <a href="../glib-Error-Reporting.html#GError"><span class="type">GError</span></a> to represent both D-Bus
errors (e.g. errors returned from the other peer) and locally
in-process generated errors.</p>
<p>To check if a returned <a href="../glib-Error-Reporting.html#GError"><span class="type">GError</span></a> is an error from a remote peer, use
<a class="link" href="gio-GDBusError.html#g-dbus-error-is-remote-error" title="g_dbus_error_is_remote_error ()"><code class="function">g_dbus_error_is_remote_error()</code></a>. To get the actual D-Bus error name,
use <a class="link" href="gio-GDBusError.html#g-dbus-error-get-remote-error" title="g_dbus_error_get_remote_error ()"><code class="function">g_dbus_error_get_remote_error()</code></a>. Before presenting an error,
always use <a class="link" href="gio-GDBusError.html#g-dbus-error-strip-remote-error" title="g_dbus_error_strip_remote_error ()"><code class="function">g_dbus_error_strip_remote_error()</code></a>.</p>
<p>In addition, facilities used to return errors to a remote peer also
use <a href="../glib-Error-Reporting.html#GError"><span class="type">GError</span></a>. See <a class="link" href="GDBusMethodInvocation.html#g-dbus-method-invocation-return-error" title="g_dbus_method_invocation_return_error ()"><code class="function">g_dbus_method_invocation_return_error()</code></a> for
discussion about how the D-Bus error name is set.</p>
<p>Applications can associate a <a href="../glib-Error-Reporting.html#GError"><span class="type">GError</span></a> error domain with a set of D-Bus errors in order to
automatically map from D-Bus errors to <a href="../glib-Error-Reporting.html#GError"><span class="type">GError</span></a> and back. This
is typically done in the function returning the <a href="../glib-Quarks.html#GQuark"><span class="type">GQuark</span></a> for the
error domain:</p>

With this setup, a D-Bus peer can transparently pass e.g. <code class="literal">FOO_BAR_ERROR_ANOTHER_ERROR</code> and
other peers will see the D-Bus error name org.project.Foo.Bar.Error.AnotherError.</p>
<p>If the other peer is using GDBus, and has registered the association with
<a class="link" href="gio-GDBusError.html#g-dbus-error-register-error-domain" title="g_dbus_error_register_error_domain ()"><code class="function">g_dbus_error_register_error_domain()</code></a> in advance (e.g. by invoking the <code class="literal">FOO_BAR_ERROR</code> quark
generation itself in the previous example) the peer will see also <code class="literal">FOO_BAR_ERROR_ANOTHER_ERROR</code> instead
of <a class="link" href="gio-GIOError.html#G-IO-ERROR-DBUS-ERROR:CAPS"><code class="literal">G_IO_ERROR_DBUS_ERROR</code></a>. Note that GDBus clients can still recover
org.project.Foo.Bar.Error.AnotherError using <a class="link" href="gio-GDBusError.html#g-dbus-error-get-remote-error" title="g_dbus_error_get_remote_error ()"><code class="function">g_dbus_error_get_remote_error()</code></a>.</p>
<p>Note that errors in the <a class="link" href="gio-GDBusError.html#G-DBUS-ERROR:CAPS" title="G_DBUS_ERROR"><code class="literal">G_DBUS_ERROR</code></a> error domain is intended only
for returning errors from a remote message bus process. Errors
generated locally in-process by e.g. <a class="link" href="GDBusConnection.html" title="GDBusConnection"><span class="type">GDBusConnection</span></a> is from the
<a class="link" href="gio-GIOError.html#G-IO-ERROR:CAPS" title="G_IO_ERROR"><code class="literal">G_IO_ERROR</code></a> domain.</p>
